Monolithic Digital IC

2-phase Brushless

LB1868

Fan Motor Driver

Overview

The LB1868 is a 2-phase unipolar brushless motor driver. With only a few peripheral parts, lockup protection and

automatic recovery can be implemented. The IC can be configured for 12V or 24V operation and a wide range of variations,

from Low speed to H-High speed and from 60cm to 120cm square using the same PCB. This makes it easy to design highly

reliable fan motor installations.

Features

• Output protection Zener diode with variable withstand voltage

Z1, Z2 pins open: V LM = 57V (24V specification)

Z1, Z2 pins shorted: V LM = 32V (12V specification)

External Zener diode connected across Z1 − V

pins: support for fans with large drive current

• External resistor allows configuration for 12V or 24V

• Direct Hall element connection possible (built-in Hall amplifier with hysteresis supports core without auxiliary electrode)

• Built-in output transistor with 1.0A output current (strengthened negative-current support for core without auxiliary electrode)

• Built-in rotation detection function: Low during rotation and High during stop

• Built-in lockup protection with automatic recovery

• Built-in thermal shutdown
